Honestly? Yes, I do think so. Ignoring the fact that Abnett really does think he's doing interesting stuff with Wally, and sometimes it's just a matter of weak writing as opposed to not having any interesting ideas, if a character is around, things can get better. I'm sure there are plenty of writers out there who love characters like these who'd love a crack at them. And even if they aren't the best, so long as nothing offensively or irreparably bad is done, things can improve for the characters.
As I already said on this thread, this argument is invalid. Because once the JSA comes back, every other era will be active.
And I'm very happy that that's the case. I've said quite a few times now that without my headcanon that everyone from Pre-FP was still living happily on New Earth, I wouldn't be able to read modern DC comics without vomiting. I have those stories of the past, and I firmly hold close that these characters I love are happy on an Earth we're no longer baring witness to.
But much like tons of others would still want more Batman and Superman stories even with that idea in mind, I still want more stories with the characters I, and plenty of others, care about.
